Flushing apparatus.



UNITED sTATEs FREDERICK OPPERMAN, OF

FLUSHING APPARATUS.

Application filed May 12,

To all whom 'it mayy concern:`

Be it known that I,- FREDERICK OPPERMAN, a citizen of the United States, and a resident of Greenwich, in the county of Fairfield and State of Connecticut, have invented certain new and useful lmprovements in Flushing Apparatus, of which the following is a specication. i

My invention relates to an improved ilushl ing apparatus for low down tanks for water closets, and it consists in certain details of construction to be more fully set forth in the following specification.

To enable others to understand my invention reference is had to the accompanying drawings, in which:

Figure 1 represents a sectional view of the tank and the cabinet or box inclosing the same, and broken view of the flush pipe and water supply pipe; and Fig. 2 is an enlarged broken sectional view of the lower part of the tank, sectional view of the casing containing the valve, piston and other mechanism, and broken view of the flush pipe and water supply pipe.

1 represents the outside wooden cabinet. 2 the water tank secured therein by the screws 3. The casing 4 has the exteriorly threaded neckor nipple 4a adapted to enter the interiorly threaded nipple 2a in the bot tom of the tank, thereby opening water communication between the interior of the tank and casing. The longitudinally operating rod 5 carries the valve 6 adapted to normally rest against the seat 7 to close communication between the tank and flushing chamber 8. The piston 9 on the inner end of rod 5 is normally located at the entrance of the piston chamberflO when the valve is seated. The outer end of rod 5 is supported in the bracket 11 and carries the spring 12 and is adapted to be actuated to unseat the valve through the medium of the bell crank lever 13 and its pulling chain 14.

15 is a removable extension of the casing 4, having the relief chamber 16 and outlet 17 to which is secured the drip pipe 17a con necting chamber 16 with the flushing chamber 8 for the purpose presently to be more fully described.

18 is the flush pipe proper secured to the casing 4.

Between the flanged portions of the casing 4 and its removable extension 15 is the disk 19 having hinged at its upper end the weighted or gravity clapper 20 normally Specification of Letters Patent.

I resting on its seat 21 to close communication between chambers 10 and `16 when the valve 9 is closed orclosing.

One very important feature of my construction is the balancing of the flushing open as easily under a high pressure as under a low pressure. This is due to the water leg or chamber 22 communicating directly with the interior of thetank 2 so that said valve and piston are always in perfect balance, for their areas being the same the pressure of water on one equals the pressure on the other. When, therefore, the rod 5 is actuated to move the valve 6 from its seat to flush, there will be no outward resistance offered to the valve whatever, and it will open, as before mentioned, as easily when the tank is full of water as when entirely empty. When the rod 5 is actuated to move the valve 6 from its seat to iiush, the piston 9 is also moved back in the chamber 10 and the slightest tendency to compress the air ahead of the piston will open the weighted valve 20, thus forcing the air, and what water may have collected in said chamber, through and into the chamber 16 and from thence into the drip pipe 17 a, and when this has been effected this weighted valve will -drop on to its seat again. Owing to this balanced condition of the valve 6, all that is necessary to flush, is to give a slight pull on the chain, when the valve will not only open easily and without resistance, but it will remain open after the chain is dropped. In other words, the chain is released after a single ilnpulse or pull to open the valve, and said valve will remain open until all the water has left the tank. When this has taken place, the spring 12 will act to close the valve slowly, and to prevent the piston being air bound on its return the needle valve 23 is provided to admit suficient air and water through the disk on partition 19 to destroy the suction in the chamber 10. Thus relieving the piston of all drag or resistance on its return. The incoming water from the supply pipe 24 will press equally against the valve 6 and piston 9 to give the. same balanced effect in closing as in opening.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is In combination with a water tank inclosed within a cabinet and having an outlet through the cabinet, of a flushing apparatus Patented oct. 26, 1909.
